This ensures that everyone's votes are accounted for. It ensures people can only vote once.

If we can track packages across the world, we should be able to track votes - making sure they don't get lost.

It will ensure to the younger community, that their vote counts.

Sticking with the bar code idea:

For people with Sensory or Conitive disabilities... If they know who they want, they could "pre-order" their bar code ticket.

They could fill in who they want... then get the ballot mailed to their house.
When they go to the polling place, they can scan their bar-code ticket, then all of the candidates they wanted to choose, get tabulated the way they wanted.

So, this idea could help with accuracy.
It can help empower people with disabilities too.
Their votes would count equally, and they could easily do it.

If the "computer-order" idea works... Everyone could place thier order on their computer. Their pre-ordered ballots then get mailed to them.

So, for people with language barriers, they can do this in their own home, then just go to the polling place and give their bar-code ticket.

For Troops over seas, they could have polling stations at their bases. Their bar codes are labeled with their home state. The computer then tabulates it for that state.

And/or for overseas troops, they all get their pre-ordered ballots with the way they want to vote. All of the bar-codes, ON BASE, then get flown together to a place in the US (Washington, DC, for instance)... then all of the ballots are scanned on US Soil. All of the ballots get casted for their own state.

The volunteers would just need to use scanning guns. The computers would be set up before the volunteers got to the polling stations - with the voter info.
